Application filed November 27, 1920. Serial No. 426,741.

To all whom it may concern.

Be it known that I, GODFREY B. l/Vn'rrsTnrN, a citizen. of Switzerland, residing at Portland, in the coiuity of Multnomah and State ofOregon, have invented new and useful Improvements in, Windows, of which the following is a specification.

This invention relates to windows, and provides a, constructionwherein both the lower and, upperfsashare permitted sliding movement, and may be also swung inwardly either singly or in unison from either side of the window casingto facilitate the washing of the window. 1 i e The nature and advantages 'of the invention will be better, understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the combination, construction and arrangement of parts as claimed.

In the drawings forming part of this application like numerals of reference indicate the similar parts in the several views and therein Figure 1 is a vertical sectional view through a window, constructed in accordance with the invention.

Figure 2 is an enlarged transverse sectional view therethrough, showing by full lines the normal position of the parts, and the adjusted position of certain parts in one of the window sashes by dotted lines.

Figure 3 is a fragmentary view showing the manner of swinging both window sashes from the window casing in the same direction.

Figure 4 is a fragmentary sectional view, showing the manner of fastening the swinging parts of the window frame together.

Figure 5 is a detail view of the window sash showing the groove to receive the usual sash weight cord.

Figure 6 is a detail view of the fastening element.

Figure 7 is a fragmentary view showing the active position of the fastening element.

Figure 8 is a perspective view of the hinge.

Referring to the drawings in detail, 10 indicates the opposed sides of the window casing while the upper and lower sashes are indicated at 11 and 12 respectively. Each sash comprises three sections, the main and intermediate section, and two side sections 13, the latter being hinged as at 14 to the intermediate section as shown. The purpose of this construction will be hereinafter described.

Arranged against each of the opposed sides 1Q of the window casing is a strip 15 which is hinged to the casing as at 16 by a three leaf hinge as shown. One leaf 17 s secured to the window casing while the intermediate leaf 18 is secured to the strip 15, the remaining leaf 19 of the hinge being secured to a relatively narrow strip 15' wh ch is arranged normally against the str1p 15. The inner edge of strip 15 is perpendicular as at 20, andthe space between this perpendicular portion 20 and'the adacent edge of the strip 15 defines a guide way in which the adjacent hinged section 13 of the sash. 12 slides. Also secured to each slde 10 of the window frame is a strip 21 which is spaced the proper distance from the perpendicular portion 20 of the strip 15 to define a guideway for the adjacent hinged sect] on 13 of the sash 11. Each of the strips 15 and 15 is provided With a slot 22, which when the strips are normally arranged are n register. The slots 22 receive a fastening element 23, the fastening element being designed to hold the strip 15 against the strip 15, fixed relatively. The fastening element 23 is mounted for rotation in said parts and is equipped with a handle or knob 24 by means of which it is operated.

The sashes 11 and 12 are mounted for independent vertical sliding movement, although one of the sashes carries fastening elements 25 designed for association with a fastening element 26 whereby the sashes may be locked when fully extended to a closed position, or when the sashes are arranged one directly behind the other. The sashes in addition to being mounted for independent sliding movement are also capable of singly swinging inwardly from either side of the window casing, or the sashes can be locked together one directly behind the other, and both of the sashes swinging as a unit inwardly from either side of the window casing. Should it be desired to swing the lowor sash inwardly from the left end side of the window casing it would be necessary to operate the fastening element 23 at the right side of the window to unfasten the strip 15, swinging the sash upon its hinge 14 at the left of the window. If both of the sashes are to be swung inwardly as a unit, the strips 15 and 15 are unfastened from the window casing and swung upon their pivots 16 as clearly illustrated. The

construction is such that the window sashes can be conveniently adjusted to facilitate washing both sides of the sashes, and there by eliminate the necessity of the personsorted to when desired as fall within the scope of what is claimed.

\Vhat claimv is 1. A window construction comprising a casing, upper and lower sashes slidably mounted on said casing, each sash including an intermediate section and hinged side sections hinged upon the opposite and corresponding edges of the intermediate section and means co-operating With said hinged sections to allow said sashes to be swung inwardly elther slngly or n unison from either side of the casing, and means for locking said sashes together, either in their normally closed position, or When arranged one behind the other. I

2. A Window construction comprising a window'casing, upper and lower sashes, a fixed strip secured to each side of saidfram'e, relatively wide and narrow'strips hingedly connected together and normallyarranged in overlapping relation at each side of the window casing, projections on said wide strips no'rmallyfinterposed between said narrow and fixed strips respectively to provide guideways in which sashes slide, said wide strips being hingedly secured to the Window casing, and means for locking said Wide and narrow strips together, each sash? including an intermediate section and hinged side sections, said side sectionsheing fitted in the guideways asand for thefpurpose.
